Preliminaries:

If your network/domain does not regularly ftp to COMET (such as does noaa.gov), you may need to request through your COMET contact that we add your IP to our allow list. If you've ftp'd in the past year or so, you might already be allowed. Give it a try, and contact us if it fails. If we must add you, we will prefer to have the IP address of the specific host from which you will ftp unless there will be several users ftp'ing to our site from your domain.

Basic Instructions for FTP'ing to COMET:

Using your ftp client of choice, open up a session to the COMET ftp site "ftp.comet.ucar.edu". In this example, we use a command-line client:

% ftp ftp.comet.ucar.edu
Log in using the user id "anonymous" and provide your own e-mail address for the password.
Type the command "bin" in order to set transfers to binary mode.

ftp> bin
Change from the current directory to the "upload" directory:

ftp> cd upload
Now, you can upload your files:

ftp> put yourfile.doc (Due to security restrctions, you will not be able to see any files in this directory, including those you 'put').
If you have many files to upload, please make a directory for your material to make it easier for COMET administrators to find and name the directory appropriately, using your last name or another name that is descriptive of the material:

ftp> mkdir yourdir ftp> cd yourdir ftp> mput *.gif (you cannot make subdirectories under the directory you create. Either zip your material and put it in your directory, or make multiple directories under "upload").
If you need to see a list of the available ftp commands, type 'help' on the ftp command-line:

ftp> help (Typing 'help <command>' will show a description of that command).
Once you are done, exit the ftp client:

ftp> bye

If you are using a graphical-interface ftp client, remember that you will not be able to see the files you place in this directory; Also, remember to check that transfers are binary.
